Abstract
The invention discloses a self-testing method for braking force of a brake, relating to the technical fields such as control of elevator traction machines and brakes, and position detection of elevator traction machines and elevator cars. The self-testing method comprises following steps: determining whether brake force detection is performed when an elevator is in the standby state, entering a self-testing program in automatic operation set by a system or in a manually operation way if so, and restoring normal operation of the elevator if not; and controlling the elevator to operate at the set speed or opening a brake to slip, driving the brake to stop a car, analyzing rotation distance of a traction machine and slipping distance of the car, calculating whether the brake is above the set value or not, stopping detection if so and normalizing the operation of the elevator; and or otherwise generating a failure code to stop the elevator. The self-testing method for braking force of the brake has following beneficial effects: the method is capable of automatically detecting whether braking force of the brake satisfies the requirement in order to avoid normal slipping phenomena caused by poor braking force; and due to failure code generated by detection, maintenance can be easily carried out by a worker in order to ensure safe operation of the elevator.
Description
Technical field
What the present invention relates to is elevator traction machine and drg control, towing machine and elevator car position detection technique field, is specifically related to a kind of self-sensing method of brake braking force.
Background technology
The braking force of current elevator machine brake has debugged before dispatching from the factory, after elevator installation puts into operation, due to the friction material wearing and tearing of drg or the aging distortion etc. of elastic element, braking force is caused to decline, thus make abnormal elevator slip ladder, cause the generation of elevator safety accident, if adopt manual operation to carry out periodic braking forces measuring to every platform elevator, need to consume the plenty of time, and operability is very low.
At present existing elevator does not just carry out the detection of braking force after putting into operation on the market, is only have attonity to monitor to drg, and for this reason, developing can the method for detection braking force size or necessary periodically automatically.
Summary of the invention
For the deficiency that prior art exists, the present invention seeks to the self-sensing method being to provide a kind of brake braking force, in elevator whole service life, regularly can automatically detect brake braking force whether to meet the demands, avoid slipping ladder because of the exception that causes of braking force deficiency, and detect the maintenance that the failure code produced facilitates workman, guarantee elevator safety operation.
To achieve these goals, the present invention realizes by the following technical solutions: a kind of self-sensing method of brake braking force, the steps include:
(1) when elevator is in readiness for action, system judges whether to need to carry out braking forces measuring, if do not do the braking force self-monitoring time to reach setting cycle, then automatically to enter by default or manual operation enters Autonomous test program, if do not need to carry out braking force Autonomous test, then terminate, elevator recovers normal and runs;
(2) control elevator to run or open drg with the Autonomous test speed of setting and slip ladder and reach Autonomous test speed, the speed of car during stop component actuation when Autonomous test speed can be set as car accidental movement;
(3) action drg, stop car;
(4) system analysis towing machine rotation distance and car sliding distance;
(5) calculate and judge whether braking force is greater than setting value, if so, then detection of end, elevator recovers normal and runs; Otherwise generation failure code, elevator is out of service.
Beneficial effect of the present invention: 1, simulate elevator slip ladder actual condition, detect the size of braking force accurately;
2, facilitate on-the-spot repair and maintenance personnel whether to meet the requirements to traction machine brake braking force to judge, detect the maintenance that the failure code produced facilitates workman;
3, periodically braking forces measuring improves the reliability of elevator brake, avoids safety misadventure, elevator safety operation is ensured.
Accompanying drawing explanation
The present invention is described in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is the flow chart of steps of the inventive method.
Detailed description of the invention
The technological means realized for making the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with detailed description of the invention, setting forth the present invention further.
With reference to Fig. 1, this detailed description of the invention is by the following technical solutions: a kind of self-sensing method of brake braking force, the steps include: that (1) is when elevator is in readiness for action, system judges whether to need to carry out braking forces measuring, if so, then Autonomous test program is automatically entered by default; Otherwise terminate, elevator recovers normal and runs; Autonomous test program also can be started by manual operation;
(2) after entering Autonomous test program, first elevator moves to end station, then runs with set Autonomous test velocity reversal, or opens drg, make elevator slip ladder and reach Autonomous test speed, the speed of car during stop component actuation when Autonomous test speed can be set as car accidental movement;
(3) under the state that elevator runs with Autonomous test speed or slip ladder brake activation action when reaching Autonomous test speed, while drg action, cut off towing machine power, stop car;
(4) system analysis towing machine rotation distance and car sliding distance in stop process, the rotation distance of towing machine can be obtained by the coder be arranged on towing machine, car sliding distance can the information of collection position reference system, or the coder be arranged on velocity limiter, or return end station by elevator and find the mode such as position and obtain;
(5) system is according to analyzing the towing machine rotation distance and the parameter such as car sliding distance and set elevator device inertia that obtain, calculate brake braking force, and judge whether calculate gained braking force is greater than set minimum value, if it is terminate braking force Autonomous test program, elevator recovers normal and runs; Otherwise fault in production code, elevator is out of service, resumes operation after detection.
This detailed description of the invention apparatus for controlling elevator carries out periodic Autonomous test according to arranging to brake braking force, carry out during nobody use of general elevator at dead of night, this Autonomous test is also undertaken by artificially triggering, by adding corresponding software on the basis of existing apparatus for controlling elevator, simulant elevator slips ladder, and brake, go out braking force size in conjunction with calculation of parameter such as elevator device inertia with towing machine rotation distance in stop process and car sliding distance.
Whether this detailed description of the invention regularly can automatically detect brake braking force and meet the demands in elevator whole service life, avoid slipping ladder because of the exception that causes of braking force deficiency, facilitate on-the-spot repair and maintenance personnel whether to meet the requirements to traction machine brake braking force to judge, detect the maintenance that the failure code produced facilitates workman, improve the reliability of elevator brake, guarantee elevator safety operation.
More than show and describe groundwork of the present invention and principal character and advantage of the present invention.The technical personnel of the industry should be understood; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof
